For the area, this is a great choice. The place is on a high floor with a nice view over the east side of the city.
The bathroom is high end as are all the other amenities. Airconditioning both in the living room and bedroom. Kitchen is fully equipped.
As the place is basically a privately owned hotel room, don’t expect any social areas or much engagement with other travelers.
Also realize the location is in the modern businessy area of Bangkok. Lots of bars and restaurants in the area, but obviously you’re not in the quaint historical area of town.
The proximity to the extremely reliable BTS SkyTrain metro system however means you can reach any part of town with ease and within the hour.
The pictures of the rooftop are from a shared access area on a lower level, that I found worth briefly visiting just once. There is however a gym and pool there which could be a major plus.
In short, highly recommended for couples or for business trips.
